Collie suffered a sprained knee after catching a pass over the middle, according to Kareem Copeland of NFL.com.
The injury is nothing new for Collie, who has battled serious concussion issues throughout his short career. In fact, the game against Jacksonville was his debut this season after having recovered from a concussion he suffered in August.
A sprained knee is not a serious injury compared to a concussion, which is an injury Collie has suffered three or more times in the past two years.
At this point, it may be time for Collie to call it quits.
Collie is doing nothing more than seriously hampering his ability to live comfortably the rest of his life. He's risking his life.
We're talking about a player that is so sensitive to lights courtesy of concussions that he now has to wear a dark visor to even step foot on the football field.
There is a point where one has to make a serious life decision—or have it done for you. Collie has arrived at the point.
The Colts organization has a responsibility to oversee the health of its players and know when they are unable to continue playing. Indianapolis needs to at least attempt to convince Collie to retire, or cut him loose to give him a wake up call.
It's not as if the Colts need Collie—they have done just fine without his services. In three years Collie has been a solid slot option, but Indianapolis has plenty of other options that have already established chemistry with rookie quarterback Andrew Luck.
Rookies T.Y. Hilton, LaVon Brazill and Donnie Avery have already surpassed Collie on the depth chart, and will continue to do so whether he is healthy or not.
Sometimes life needs to be put into perspective. Perhaps Collie wants to continue playing no matter what, and does not care about the consequences. It may even be possible the organization has already had a serious talk with him.
Regardless of what has happened to this point and what doctors have said, the time is now for Collie. He's 26 years old and has made plenty of money in his football career. Collie is young enough to move on to better things and not risk his health.
In the grand scheme of things, football is not actually important. Football fans are selfish, and there will be those that will be angry for Collie calling it quits early—but those are the ones that need things put into perspective.
Austin Collie must retire. If he won't, the Colts organization needs to do the right thing and force his hand.
There are bigger things in life than football, and Collie needs to get out now in order to experience it.
